Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is further described.Following examples are only for the technical solution of the utility model more clearly is described, and can not limit protection domain of the present utility model with this.
As shown in the drawings, a kind of oil filter, comprise frame 1, the cover plate be fixedly connected with described frame 1, be arranged at the element kit in described frame 1, offer oil inlet hole 2 and oil outlet 3 on described cover plate, form the oil inlet passage 4 be connected with described oil inlet hole 2 between described frame 1 and described element kit, form the oil discharge passage 5 be connected with described oil outlet 3 in described element kit, front cover 7 and rear end cover 8 that described element kit comprises outer filter core 6 and is arranged at described outer filter core 6 two ends, described oil inlet passage 4 is positioned at the outside of described outer filter core 6, described oil discharge passage 5 is positioned at the inboard of described outer filter core 6, offer the connection mouth 9 that is communicated with described oil inlet passage 4 and described oil discharge passage 5 on described rear end cover 8, described connection mouth 9 places are provided with bypass valve, described element kit also comprises inner filter core 10, described inner filter core 10 is arranged in described oil discharge passage 5, described inner filter core 10 is connected with described connection mouth 9 by described bypass valve, as shown in Figure 1, described cover plate is cylindrical, described oil inlet hole 2 has eight, described oil outlet 3 is one, the center line of described oil outlet 3 and the center line of described cover plate coincide, eight described oil inlet holes 2 are evenly distributed on take on the circumference that the center of described oil outlet 3 is the center of circle, and the number of oil inlet hole 2 is not limited to the numerical value that the present embodiment provides in addition.
Without diagram, the filter opening of described outer filter core 6 is less than the filter opening of described inner filter core 10, and the aperture of the filter opening of described outer filter core 6 is the 65-85 micron, and the aperture of the filter opening of described inner filter core 10 is the 120-130 micron.After outer filter core 6 stops up; machine oil filters and just the impurity of larger particles is carried out to rough filtration by inner filter core 10; not reach the filtering effect of outer filter core 6, the utility model is only to play in the situation that the user does not change outer filter core 6, the effect of temporary protection in time.
As shown in Figure 2, described bypass valve comprises male portion 11, with described male portion 11, slides mutually the catch 12 that can block described connection mouth 9 is set, and between described male portion 11 and described catch 12, is provided with return springs 13.After outer filter core 6 stops up, machine oil in oil inlet passage 4 is more and more, oil pressure in it is also increasing, when oily pressure is greater than the elastic force of return springs 13, catch 12 is backed down with connection mouth 9 to be separated, now machine oil enters inner filter core 10 from connection mouth 9, after the filtration of inner filter core 10, from oil discharge passage 5, flows out again.Its machine oil flows to schematic diagram as shown in Figure 5, when outer filter core 6 is not blocked, machine oil in oil inlet passage 4, flow through filter core 6 filter, then, directly from the interior outflow of oil discharge passage 5, its machine oil flows to schematic diagram as shown in Figure 4.
